Abstract

The invention discloses a purification method for rural domestic sewage and a stepped sewage percolation purification system. According to the invention, domestic sewage is discharged to a sewage collection pool, then the stepped sewage percolation purification system is arranged along a ramp located below the sewage collection pool; the stepped sewage percolation purification system is composed of multiple steps of wetland percolation water purification systems arranged in a step or terrace mode, each step of the wetland percolation water purification system is provided with a percolation water purification layer and a surface soil layer, wetland plants are planted in soil of the surface soil layer, and when discharged domestic sewage passes through the stepped sewage percolation purification system, biological absorption and percolation purification are carried out so as to realize purification of the domestic sewage. The invention has the following advantages: simple process, low capital construction cost, easy management and protection, no pollution, a good removal effect on rural domestic sewage, high ornamental values and economic values of planted landscape plants, medicinal plants and food plants, and suitability for purification of rural domestic sewage in mountain areas.

Description

technical field [0001] The invention relates to a method for purifying rural domestic sewage and a stepped sewage percolation purification system, belonging to the technical field of purification treatment of rural domestic sewage, especially rural domestic sewage in mountainous areas. Background technique [0002] As the country pays more attention to point source pollution caused by industrial sewage discharge, agricultural non-point source pollution and rural domestic sewage pollution have gradually become the main source of eutrophication in river water. The high nitrogen and phosphorus content in the water body will cause massive growth of algae and cause the death of a large number of aquatic plants and fish. Rural domestic sewage is the sewage produced by households in villages and towns from washing, bathing, cooking in the kitchen, excrement and its washing. Rural domestic sewage has the characteristics of wide dispersion, multiple sources, rapid growth, complex s...
